Earnings Per Share [Abstract] |
Loss Per Share |
11. | LOSS PER SHARE
The Company’s basic loss per common share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. The Company’s restricted stock awards (non-vested shares) are issued and outstanding at the time of grant but are excluded from the Company’s computation of weighted-average shares outstanding in the determination of basic loss per share until vesting occurs. A net loss cannot be diluted, so when the Company is in a net loss position, basic and diluted loss per common share are the same. If in the future the Company achieves profitability, the denominator of a diluted earnings per common share calculation will include both the weighted-average number of shares outstanding and the number of common stock equivalents, if the inclusion of such common stock equivalents would be dilutive. Dilutive common stock equivalents potentially include warrants, stock options and non-vested restricted stock awards and units using the treasury stock method, along with the effect, if any, from the potential conversion of outstanding securities, such as convertible preferred stock. The following potentially dilutive securities outstanding as of September 30, 2018 and 2017 have been excluded from the denominator of the diluted loss per share of common stock outstanding calculation (in thousands):
|  | September 30, |
|  | 2018 |  |  | 2017 |
Stock options |  |  | 2,873 |  |  |  | 2,305 |
Non-vested restricted stock awards |  |  | 7 |  |  |  | 15 |
Non-vested restricted stock units |  |  | 38 |  |  |  | - |
Convertible preferred stock warrants |  |  | - |  |  |  | 85 |
Common stock warrants |  |  | 105 |  |  |  | - |
